| I bought it once from ebay as part of a package. For $20, I got a cellphone battery, charger, leather case and the so-called antenna booster.
I don't know how it works, but it's just a plastic sticker with some "sophisticated looking" markings that were printed on it using some metallic ink. The print did rub off after a few days. I removed the sticker because I wasn't convinced it really made any difference, and in fact cheapened the appearance of my otherwise chic-looking Nokia 8260.
I tried it because it came 'free' with the rest of the bundle, but I wouldn't shell out $25 for it unless someone can prove it really works. |
